April and May: every week, no exceptions
Cool-season grass grows hardest in spring. Skip a week in May and you're scalping the lawn on the next visit, which stresses it right before summer heat.

How Often Should You Mow a Lawn in Massachusetts?
Weekly in June, every other week in August. Here's why the calendar matters less than the grass.
The rule people repeat is 'never take off more than a third of the blade at once.' That rule is right, and it's also the whole answer - how often you mow just depends on how fast your grass is growing that week.
Here's what that looks like in practice on a Norfolk County lawn.
02
June and July: weekly, and raise the deck
Cut at three and a half inches or higher. Taller grass shades its own roots, holds moisture and crowds out crabgrass better than any product you can buy.
03
August: every other week is usually fine
Growth slows in the heat. Cutting a dormant lawn on a schedule does more harm than good, so we adjust rather than mow for the sake of the invoice.
04
September and October: back to weekly
The fall flush is the best growing window of the year. Regular cuts plus aeration and overseeding now is what makes next spring easy.
05
Leave the clippings
Mulched clippings put roughly a quarter of your lawn's nitrogen back into the soil for free. We only bag when the growth got ahead of us.
We mow weekly through the growing season and adjust in the dry weeks. That flexibility is included, not an upcharge.
